Australia's variable rainfall - how dry or wet can it really get? Australia’s rainfall is extremely variable, which means existing weather records are too short to calculate the true risk posed by droughts and floods. This project aims to quantify how naturally variable the rainfall coming from the Indo-Pacific mid-latitudes is, allowing recent rainfall extremes and future projections to be assessed in a long-term context. This project expects to produce new estimates of atmospheric moisture bud ....Australia's variable rainfall - how dry or wet can it really get? Australia’s rainfall is extremely variable, which means existing weather records are too short to calculate the true risk posed by droughts and floods. This project aims to quantify how naturally variable the rainfall coming from the Indo-Pacific mid-latitudes is, allowing recent rainfall extremes and future projections to be assessed in a long-term context. This project expects to produce new estimates of atmospheric moisture budgets between Australia and Antarctica based on a novel, 1000-year length reconstruction of moisture-bearing southern Indian Ocean storms. This new information is critically needed by water managers so that they can properly calculate (and ultimately prepare for) the worst of Australia’s rainfall-related risks.Read moreRead less
ARC Centre of Excellence for Climate Extremes. This Centre aims to transform understanding of past and present climate extremes and revolutionise Australia’s capability to predict them into the future. Climate extremes cost Australia up to $4 billion a year and will intensify over coming decades.

Southern Ocean aerosols: sources, sinks and impact on cloud properties. This project aims to provide fundamental process-level understanding of atmospheric aerosol processes over the Southern Ocean, a region that has a profound influence on the Australian and global climate and where climate models perform poorly. Comprehensive observations during 3 Southern Ocean voyages and land-based measurements will enhance our knowledge of aerosols and cloud formation in that region and provide much-needed ....Southern Ocean aerosols: sources, sinks and impact on cloud properties. This project aims to provide fundamental process-level understanding of atmospheric aerosol processes over the Southern Ocean, a region that has a profound influence on the Australian and global climate and where climate models perform poorly. Comprehensive observations during 3 Southern Ocean voyages and land-based measurements will enhance our knowledge of aerosols and cloud formation in that region and provide much-needed data for improving global climate models. Expected outcomes include more accurate seasonal and latitudinal representations of Southern Ocean aerosol populations, properties and sources. The main benefit includes improvements in weather forecasting and future climate projection for Australia and the Southern Hemisphere.Read moreRead less
Tracking flood waters over Australia using space gravity data. This project aims to assess the utility of near-real-time data from the currently operating space gravity satellite mission to quantify and track flood waters in Australia. Through analysis of the satellite data and fusion of observed signals with rainfall, river flows and conventional hydrological modelling, it expects to create new knowledge of soil moisture and movement of flood waters.

This project aims to assess the utility of near-real-time data from the currently operating space gravity satellite mission to quantify and track flood waters in Australia. Through analysis of the satellite data and fusion of observed signals with rainfall, river flows and conventional hydrological modelling, it expects to create new knowledge of soil moisture and movement of flood waters. Expected outcomes include a capability to improve hydrological models by including the information of water signals obtained from the near-real-time observations. This should provide significant benefits such as more accurate land saturation maps and better predictions of runoff and flood risk.Read moreRead less

Improving water quality modelling by better understanding solute transport. Poor stream water quality is a critical problem in Australia and globally. Stream water quality depends directly on pathways and time taken for water to transport pollutants through catchments. Predicting these pathways is highly challenging and currently requires specialised data.

Poor stream water quality is a critical problem in Australia and globally. Stream water quality depends directly on pathways and time taken for water to transport pollutants through catchments. Predicting these pathways is highly challenging and currently requires specialised data. This project aims to better model the movement of water from rainfall to streams, enable greatly improved use of water quality data routinely collected in Australia's catchments and thereby better predict water quality behaviour. Proposed field studies aim to support this development. The outcomes sought are improved planning and management of water quality in our rivers, lakes and estuaries, improved health of these water bodies and improved water supplies.Read moreRead less

Unravelling the dominant drivers of ion specificity. This project aims to understand what governs the sensitivity of many technological and biological processes to the precise nature of the salt present in solution. The term ‘ion-specific’ encompasses all the circumstances in which the influence of a salt in solution depends on the precise chemical nature of the salt, not just the electrical charge on the ions that form the salt. As such, ion-specific effects abound and have important consequenc ....Unravelling the dominant drivers of ion specificity. This project aims to understand what governs the sensitivity of many technological and biological processes to the precise nature of the salt present in solution. The term ‘ion-specific’ encompasses all the circumstances in which the influence of a salt in solution depends on the precise chemical nature of the salt, not just the electrical charge on the ions that form the salt. As such, ion-specific effects abound and have important consequences in most situations involving solutions, including cellular functions and battery technology. This project will enable us to understand and control the influence of specific ions, building on our recently described fundamental ion-specific series with colloid science experiments and quantum simulations. This project should overcome current challenges in predicting ion-specific effects leading to progress in a wide variety of applications of colloid and interface science, from sensor interfaces to self-assembly.Read moreRead less

Summary
How will Pacific climate variability impact Australia in a warming world? Temperature variability in the Pacific Ocean is characterised by El Niño and La Niña (year-to-year variations) and the Interdecadal Pacific Oscillation (decadal variations). These phenomena are primary drivers of Australian temperature and rainfall. Leveraging new tools and methods, including Single Model Initial-Condition Large Ensembles, this project will investigate drivers of these phenomena, and their impacts on Austr ....How will Pacific climate variability impact Australia in a warming world? Temperature variability in the Pacific Ocean is characterised by El Niño and La Niña (year-to-year variations) and the Interdecadal Pacific Oscillation (decadal variations). These phenomena are primary drivers of Australian temperature and rainfall. Leveraging new tools and methods, including Single Model Initial-Condition Large Ensembles, this project will investigate drivers of these phenomena, and their impacts on Australia in a warming world. Outcomes include the quantification of how these climate phenomena modulate extreme weather events, and an understanding of how Indian and Atlantic Ocean warming affects the Pacific region. This will improve the prediction of extreme events, which is critical for preparation for their impacts.Read moreRead less
